Description

Technical Field

[0001] This utility model relates to the field of gas valve technology, specifically to a switch-driven gas valve. Background Technology

[0002] Gas valves are safety devices in gas pipeline engineering, mainly used to cut off, connect, and regulate the flow of gas media. They are suitable for pipeline systems of coal gas, liquefied petroleum gas, natural gas, etc. Gas valves control the gas supply and demand through manual, electric, or pneumatic means to ensure gas safety. For example, when the gas pressure is abnormal or the hose comes loose, some models will automatically close to prevent leakage. Switch-driven gas valves are devices that drive the gas valve to open or close through external control signals, mainly used to control the gas supply and demand.

[0003] Existing gas valves have some drawbacks: First, they are not easy to open and close, and the operation is cumbersome, causing inconvenience to users; second, they are not easy to disassemble and maintain, and consume labor. Utility Model Content

[0004] The purpose of this invention is to provide a switch-driven gas valve to solve the problems mentioned in the background art, such as difficulty in opening and closing, and inconvenience in disassembly and maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a switch-driven gas valve, comprising a valve cover and a valve body. The valve cover is disposed on the upper end of the valve body, and a sealing cover is fixed to the upper end of the valve cover. A gear 1 is rotatably connected to the upper end of the sealing cover, and a motor is fixed to the lower end of the sealing cover. The output end of the motor is fixedly connected to the driving end of the gear 1. A gear 2 is rotatably connected to the upper end of the valve cover, and one side of the gear 2 meshes with one side of the gear 1. A threaded post is threadedly fitted inside the gear 2 and at the upper end of the valve cover, and a valve stem is disposed at the lower end of the threaded post. Packing is disposed inside the valve body corresponding to the valve stem. A valve disc is fixed to the lower end of the valve stem. The motor is controlled by an external switch. The output end of the motor drives the gear 1 to rotate, which in turn drives the gear 2 to rotate, thereby causing the threaded post to rise and fall, which in turn causes the valve stem to rise and fall, and consequently the valve disc to rise and fall. When the valve disc falls, it can block the gas flow path, thereby closing the gas valve; conversely, it can open the gas valve, thereby achieving on / off control of the gas valve.

[0006] As a further technical solution of this utility model, a valve seat is provided in the middle of the valve body corresponding to the valve disc, and insert blocks are fixed on both sides of the upper end of the valve body.

[0007] As a further technical solution of this utility model, slots are provided on both sides of the lower end of the valve cover, and the slots are engaged with the insert blocks, so that the insert blocks can be inserted into the slots, thereby realizing the rapid assembly between the valve cover and the valve body.

[0008] As a further technical solution of this utility model, both ends of the valve cover are threaded with bolts, and one end of the bolt is threaded with the insert block, so that the bolt can be screwed into the valve cover and the insert block is screwed into it to install the valve cover and valve body.

[0009] As a further technical solution of this utility model, one end of the valve body is provided with an inlet and the other end of the valve body is provided with an outlet. When the valve disc is raised, the gas can enter the interior of the valve body from the inlet and flow out through the outlet, so as to realize the normal flow of gas.

[0010] As a further technical solution of this utility model, a sealing ring one is provided at the upper end of the valve body, and a sealing ring two is provided at the lower end of the valve cover. Both sealing ring one and sealing ring two are made of wear-resistant and corrosion-resistant materials to improve the sealing effect and extend the service life. The packing is PTFE packing, which can effectively prevent gas leakage and further improve the sealing performance of the gas valve.

[0011] As a further technical solution of this utility model, both ends of the valve cover are hinged with protective covers, and a magnetic block is provided at the lower end of one side of the protective cover. The protective cover can protect the inside of the threaded grooves corresponding to the bolts and the valve cover, reducing dust accumulation.

[0012] As a further technical solution of this utility model, magnetic blocks II are provided at the lower ends of both sides of the valve cover. Magnetic blocks II are magnetically connected to magnetic blocks I, so that two protective covers can be placed on both ends of the valve cover. Magnetic blocks II and magnetic blocks I are magnetically attracted to each other, so that the protective covers are stably placed on the outside of the bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are: When the valve disc rises, gas can enter the valve body from the inlet and flow out through the outlet, achieving normal gas flow. An external switch controls the motor to operate. The motor's output drives gear one to rotate, which in turn drives gear two to rotate, thereby raising and lowering the threaded column, causing the valve stem to rise and fall, and consequently, the valve disc to rise and fall together. When the valve disc falls, it can block the gas flow path, thus closing the gas valve; conversely, it can open the gas valve. This achieves on / off control of the gas valve. Furthermore, both sealing rings one and two are made of wear-resistant and corrosion-resistant materials to improve the sealing effect and extend the service life. Additionally, the packing is PTFE packing, which can effectively prevent gas leakage, further improving the sealing performance of the gas valve and making it easy to open and close. By inserting the insert into the slot, the valve cover and valve body can be quickly assembled. Bolts can be screwed into the valve cover, so that the bolts are screwed into the insert, and the valve cover and valve body can be installed. Afterwards, two protective covers can be placed on both ends of the valve cover. Magnetic block two and magnetic block one attract each other, so that the protective cover is stably covered on the outside of the bolt. The protective cover can protect the inside of the corresponding thread groove of the bolt and valve cover, reduce dust accumulation, and facilitate disassembly and maintenance.

[0018] Please see Figure 1-5An embodiment of this utility model provides: a switch-driven gas valve, including a valve cover 6 and a valve body 10. The valve cover 6 is disposed on the upper end of the valve body 10. A sealing cover 5 is fixed to the upper end of the valve cover 6, and a gear 1 2 is rotatably connected to the upper end of the sealing cover 5. A motor 1 is fixed to the lower end of the sealing cover 5, and the output end of the motor 1 is fixedly connected to the driving end of the gear 1 2. A gear 2 3 is rotatably connected to the upper end of the valve cover 6, and one side of the gear 2 3 meshes with one side of the gear 1 2. A threaded post 4 is threadedly fitted inside the gear 2 3 and the upper end of the valve cover 6, and a valve stem 14 is disposed at the lower end of the threaded post 4. A packing 7 is disposed inside the valve body 10 corresponding to the valve stem 14, and a valve disc 16 is fixed to the lower end of the valve stem 14. Specifically, such as Figure 1 and Figure 5 As shown, the motor 1 is controlled by an external switch. The output end of the motor 1 drives the gear 2 to rotate, which in turn drives the gear 3 to rotate, thereby driving the threaded column 4 to rise and fall, causing the valve stem 14 to rise and fall, which in turn causes the valve disc 16 to rise and fall together. When the valve disc 16 falls, it can block the gas flow path and close the gas valve. Conversely, it opens the gas valve, thus realizing the on / off control of the gas valve.

[0019] A valve seat 15 is provided in the middle of the valve body 10 corresponding to the valve disc 16. Insert blocks 8 are fixed on both sides of the upper end of the valve body 10. Slots 18 are provided on both sides of the lower end of the valve cover 6, and the slots 18 are engaged with the insert blocks 8. Specifically, such as Figure 1 and Figure 2 As shown, the insert 8 can be inserted into the slot 18, enabling quick assembly between the valve cover 6 and the valve body 10.

[0020] Both ends of the valve cover 6 are threaded with bolts 19, and one end of the bolts 19 is threaded with the insert block 8; Specifically, such as Figure 1 and Figure 3 As shown, bolts 19 can be screwed into valve cover 6 so that bolts 19 are screwed into insert block 8, thereby installing valve cover 6 and valve body 10.

[0021] One end of the valve body 10 is provided with an inlet 17, and the other end of the valve body 10 is provided with an outlet 11; Specifically, such as Figure 1 and Figure 2 As shown, when valve disc 16 rises, gas can enter the valve body 10 from inlet 17 and flow out through outlet 11, thus achieving normal gas flow. A sealing ring 12 is provided at the upper end of the valve body 10, and a sealing ring 2 13 is provided at the lower end of the valve cover 6. Specifically, such as Figure 1 and Figure 2As shown, both sealing ring 12 and sealing ring 13 are made of wear-resistant and corrosion-resistant materials to improve the sealing effect and extend the service life. Subsequently, the packing 7 is PTFE packing, which can effectively prevent gas leakage and further improve the sealing performance of the gas valve.

[0022] Both ends of the valve cover 6 are hinged with protective covers 9, and a magnetic block 20 is provided at the lower end of one side of the protective cover 9. Specifically, such as Figure 1 and Figure 2 As shown, the protective cover 9 can protect the inside of the threaded grooves corresponding to the bolt 1 and the valve cover 6, reducing dust accumulation.

[0023] Magnetic blocks 21 are provided at the lower ends of both sides of the valve cover 6, and magnetic blocks 21 are magnetically connected to magnetic blocks 20. Specifically, such as Figure 1 and Figure 2 As shown, two protective covers 9 can be placed over both ends of the valve cover 6, and magnetic block 21 and magnetic block 20 magnetically attract each other, so that the protective cover 9 is stably placed over the outside of the bolt 19.

[0024] Working principle: In use, the insert block 8 can be inserted into the slot 18, realizing the quick assembly between the valve cover 6 and the valve body 10. The bolt 19 can be screwed into the valve cover 6, so that the bolt 19 is screwed into the insert block 8, and the valve cover 6 and the valve body 10 are installed. After that, two protective covers 9 can be placed on both ends of the valve cover 6. The magnetic block 21 and the magnetic block 20 attract each other, so that the protective cover 9 is stably covered on the outside of the bolt 19. The protective cover 9 can protect the inside of the corresponding thread groove of the bolt 1 and the valve cover 6, reducing dust accumulation. Then, when the valve disc 16 rises, the gas can enter the valve body 10 from the inlet 17 and flow out through the outlet 11, realizing the normal flow of gas. The electric circuit is controlled by an external switch. When motor 1 is running, the output end of motor 1 drives gear 2 to rotate, which in turn drives gear 3 to rotate, thereby causing the threaded column 4 to rise and fall, which in turn causes valve stem 14 to rise and fall, and valve disc 16 to rise and fall together. When valve disc 16 falls, it can block the gas flow path and close the gas valve; conversely, it can open the gas valve. Thus, the gas valve can be controlled to open and close. In addition, sealing rings 12 and 13 are made of wear-resistant and corrosion-resistant materials to improve the sealing effect and extend the service life. Furthermore, the packing 7 is PTFE packing, which can effectively prevent gas leakage and further improve the sealing performance of the gas valve. In summary, this gas valve is easy to open and close, and easy to disassemble and maintain.
